DOFFING AND DONNING- vTlflilCIE-IAll'ISll/l.

To all w/Lom t may concern Be it known that I, HUGH P. EANES, a citizen of the United States, residing at Martinsville, in the county of Henry and State of Virginia, have invented certain new and useful Improvements in Dofiing and Donning Mechanism, of which the following is a specification.

My invention comprises improvements in doiiing and donning mechanism, the principles of which are adapted for embodiment either in attachments to spinning frames or in portable organizations or machines adapted to be carried or moved about from one spinning frame to another, preferably the former.

There are several objects. One is to do by machinery what heretofore has been done only by hand. Another object is to provide means for the automatic feed of empty bobbins or quills to donning appliances wheref upon they are placed mechanically upon the spindles upon which they are to be mounted, and another object is to provide means for removing the filled bobbins or quills. from the said spindles and conveying them away. Another object is to provide a machine of simple mechanism which will accomplish all of this with the fewest possible number of parts and with the least expenditure of power.

In the accompanying drawings,

Figure l, is a plan view of aportion` of a machine, showing three spindleswith cooperating donners and doffers, the center one with more or less of its mechanism for actuating the parts,

Figure 2, is an enlarged transverse section through the feed trough and belt,

Figure 3, is an enlarged fragmentary view of one unit of the mechanism,

Figure t, is a view of the same from the side,

from the opposite side of the machine, showing the doifer in position to remove a bobbin or quill,

Figure 12, is a view-in perspective of the bobbin or quill control.

Figs. 13 to 16, inclusive, are detail views showing mainly the cam and lever arrangements of the machine.

Fig. 17 is a .detail view of the rockers 54:,

54C, and certain associated parts.

The clotting and donning appliances, as many Vas required, are arranged in batteries of as `many units as required for thework, all operated by a single shaft, but as these macliinesor units areall alike only one will, for the most part, be described..

The numeral 1, represents the base, and2, represents brackets, of which there are two for each unit. These are rigidlyY secured at one end andthey converge toward the other Iend in the general direction ofthe .spind'lef lThese brackets 2, form supportfor all of the working parts of themachine. A maincam shaft 4, is journalled in these'brackets `di reetly above the base. thesecams, namely 5, 6, 7,' and 8, and these are held adjustably in positionon the shaft, by meansfof nuts 9, which are adapted to 'be screwed up tight against either side of lthe caiiis, on .the threads ofthe shaft 41. f The office Vof these cams will be fullyexplained hereinafter. l The donner consists preferably of Jtwo jaws 10,.and 11 carried onthe outer end of the larm 12. `Jaw 10,-is lined tothe outer end of ther arm V,and the jaw 11, is pivoted on a pin 13, and av spring .14, normally'holds these jaws closed, as shown'in Figure 3, which-is the position when gripping a-bobbin or quill.- The arm 12, is slotted nearly throughout its entire length by a lslot '15. Two rocker arms 16, and 17, are piyotally mounted. on the-inner sideoflonenofthe brackets 2, and rivets 18, eXtend.- through thev upper ends yof ,these rockers, ,through There are Afour 0f tlf) the slot 15, and are secured to the plate 19, which extends parallel with the arm and in contact with it for a portion of its length, as shown in Figure 7, the forward end 20, however forming a trip, in position to en gage a projection 21, on the rear end of the pivoted jaw 11, when the bobbin or quill is to be dropped from the donner, which is the position of parts shown iii Figure 7. A stiff spring 22, extends from the lower end of rocker 16, toa stud 23, on the bracket 2, for restoring the rockers to their upright or normal position, and a spring 24, eX- tends from some point at the forward end of the machine, for example the cross bolt 25, to the lower end of the tappet 26, which has the effect of pulling the upper' end of the tappet back, and with it the arm 12, as the upper or free end of the tappet is hooked around a stud 27, which 'projects laterally from'the rearend of the arm 12. This tappet 26, has the douhle function of pushing and pulling the arm 12. Tt has an anti-friction roller 28, on one side in the path of the Cain 5, so that as the latter makes a revolution, it swings the tappet forward against vthe stud 27, against the tension of the spring 24, andA into the position shown in Figure 11. With the further rotation of the cam shaft 4, the concentric portion of l the'cam 5, traverses or turns upon the roller 28, and during this transit which holds the donner in this position shown in Figure 11, the cam 6,v commences to brush against the roller 29, on the side of a second tappet 30, pushing it forward against a laterally projectingstud 31, on the plate 19. rThis has the effect of slidingthe plate 19, forward and by tilting the roekers 16, and 17, it lowers the donner, over the spindle 3. A trip 32, is formed on the forward end of plate 19, and this trip is thrust against the tongue 33, on the pivoted jaw 11, thereby opening the jaw and releasing the bobbin or quill upon the spindle 3. The further turning of the cam shaft withdraws cam 5, from the path of the tappet 26, and moves cam 6, from the roller 29, on the'second Y tappet 30, whereupon the spring 24, which has been placedunder tension, immediately returns the donner, plate and rockers to their normal positions, or in place vfor the donner to receive another bobbinv or quill, preparatory to its delivery to the spindle.

The bobbins or quills are fed to a whole battery vof donners from a hopper 34, througha trough 3 5, upon a moving belt 36,

.the latter travelling over` rollers 37, onel of which is ldriven by the shaft 33, through bevel gears 39, and 40, from the main cam Y shaft 4, on one end of which' the latter gear is keyed.

There is a'spout 41, leading from the forward side of the trough for each donner,

anda tapering or conical roller 42, beneath the belt 36, opposite each spout, causes the discharge of the bobbins or quills into these spouts and thence into the donner if below as in Figure 1. Two gates 43, and 44, are secured to a common shaft 45, one above and the other below, the plane of the donner, and one of these gates, namely 44, closes the bottom of the donner, when the latter is in position to receive a quill as shown in Figures 1, and 4, and the upper gate 43, is designed to close the spout 41, while the donner is carrying its bobbin or quill to the spindle 3. So these two gates operate simultaneously but they alternately close the bottom of the donner and spout. The shaft 45, is supported in a bracket 46, on the outer/ end of one of the main brackets 2. `A spring 47, normally rocks the shaft 45, to swing the gates 43, beneath the spouts as shown in Figure 9. The moment the donner recedes from the spindle 3, a stop 48, on its side strikes a stud 49,- on the shaft 45, and turns the shaft 45, part way around, swinging the gate 43, `from beneath the spout and gate 44, beneath the donner, thus providing a temporary bottom for it, while receiving another bobbin or quill, and until the donner starts forward, when the tongue 33, on the movable jaw v11, leaves the trip 32,and the jaw closes upon the bobbin or quill and the gate 43 swings beneath-the spout 41, above, thus holding back the bobbins or quills until the donner is again empty and back in place to receive another bobbin or quill.

' The doffer is in the form of a pair of spring gaws 50. `These are on the Voutei end of anA arm 51, which 'has a slot 52 eX- tending nearly its entire length, which receives the screws 53 which extend therethrough from the upper ends of the rockers which latter are pivoted at their lower ends .to one of the brackets 2, as shown in Fig. 6. These screws after extending through slot 52 are connected to a. plate and from this'plate a stud 56 extends lat-7 l orally, and another stud 57 extends'laterally from the rear end of the arm itself. These two studs are in thepath of tappets 5S and 59 respectively, and these tappets have aiiti-friction rollers 60 and 61 thereon in the path of the cams 7 and 6 on the main shaft 4, so that the several cams on the camshaft are so arranged and timed with respect to one another that the donner and dofi'ei' alternate, one in order to place the bobbin or quil upon the spindle' 3, and the A. small cam 62 gives Va slight forward 'iis movement to the doier to slacken the thread, while the donner is placing the bobbin or quill upon the spindle 3. This cam 62 is located in line with and opposite the cam 8.

A stripper Get is secured to bracket 2 in position to strip the bobbin or quill from the do'er when the latter resumes its rearward or normal position.

A spring G5 holds these parts under ten-A sion, and a spring 66 extends irom the lower end of one of the rockers 54 to a point on the bracket 2 to assist in returning the doffer to its normal position.

From the doffer, the bobbins or quills are dropped to the lower portion of the belt 36, and thence out through an opening 68 (see rig. i0).

Thus it will be seen that the entire operation is automatic, namely that the bobbins or quills are fed into the donner, deposited by the latter on the spindle, then wound or spooled, this latter operation being old and well-lmown and not shown, then removed v by the doiier and dropped upon the belt and conveyed to a receptacle 69 therefrom.

The cam-shaft 4 is actuated intermittently in any approved manner, and these donners and dofi'ers are arranged in pairs and in batteries or" as many as required to do the worl, all being actuated by the common cam-shaft t.
